T0 ,ALL WHO'M IT MAY CONCERN:

Be it known that I, Jeux B. JoHNsoN, of Laurel, in the county of Franklin,'and State of Indiana-'have invented `an Impiovemeut in Automatic Car-Couplings; and I do hereby declare that thefollowing is. a full, clear, and exact description of the same, reference being had t`o the vannexed drawings, making part ot' this specification, in which-il vFigure 1 is a perspeolve` view, and

Figure 2 is a vertical section.

The same letters are employed in both g'uros'in the indication of the same parts'. This improvement relates to 'a coupling'by which railroad-cans maybe automatically connected, and con-v sists in a novel combination of parts, as set forth in the following description and claims."

In the-annexed drawings, A. is the drawbar, with a chambereil draw-head' to reeeii'c'the coupling-link. A l

spring, formed from a strip of elastic sheet metal, is bolted to the upper part of 'the.dauw-beati,` and being curved downwards, rests looselyat the other end upon the' bottom of the duwt-head.V It has c. hole -through it at the proper-point for the-introduction oi' the cnuplingpin C which passesthrough the draw-head. D is a pin which, resting upon the top of' the spring B, near to its lower endprojeet s through shole in the .top of the draw-head. The lever E is attached tothe top of thejdraw-head, and projectlnglaterally, rests upon the upper end of the'pin D." This leve is attached, by a'ehain or cord, E', to a wheel, F,a't or near the periphery. This wheel turns freely uponits axis, and is also connected with the coupling-'puin by a cord or chain, C'. Another eordor chain, G, attached to the periphery of the wheel, is carried to the top of the car.

The operation of the coupling is asio'llows': The' weight of the .lever E `musi: b enioi'e than suflicient to counterbalance that'of the coupling-pin, -the chains connecting the two with thewhee'l :being attached on the, opposite sides thereof. When'` the liu'k' is'not.ins erted, the spring B rests uponjthe'lhottom of the draw-head,

and the pin Disdepressed, so as to allow'the leve-r to'descend and hold suspended the coupling-pin. Wheuthe linkepters the draw-head passing under the spring B, it forces it upw ards,'and with it the-'pinll and also the'v lever E, which Vis-suppox'tcd upon the pin D. The weightofthe lever being Athi1stake-n from the wheel F, it

will turn upon'its axis by the wei'ghbot the coupling-pin suspended/on the opposite .sidofand the pin will fall" Vthrough the link and the lower hole in thedrawfhead. '.Tho weghtfof thelever pressing upon the spring will assist -its tension in holding thelinlz, which must be elongated on theonds, in a horizontal .pdsitiom'nnd .i'nfthe right direction to enter anotherdraw-head in eouplinga traino'f cars." :The'cais may be uneoupled from the top by drawing upon the 'chain G, to lift'the coupling-pin', out 'of the li'nlc.

I t is sometimes desirablethat oarsl pushed together should not be'coupled automatically. This is provided lfor by either hooking up -theehaih G. and holding the pin.' suspended, or by lifting the pin vout ot`the dran'- head hy hand.V

What I claim as myinvention, and desire te secure by Letters Patent, isv y 1. The combination of the spring B, pinD,` lever E, and wh'eel F, and'chlains Ef and C', withthe pin' and link of a raiload-eai',substantially as set` forth. i i

2. Snspending the coupling-pin '0. from a wheel, on the opposite side of wli'ichwis a'levor suspended, so as to more than conterbalance the weight ol' the pin, when said lover is so'supportoddhahhy the entrance ofthe link into the draw-l1ead, the pin, -released from the weight ofthe lever, will fall by its own guravity'auhstantally as set forth. p l i In testimony whereof, I have signed my name to this speciucntion io the presence oi two subscribing witnesses.
